Have a friend or family member who is showing signs of hearing loss?

In “Hearing loss: Listening to the signs,” Treva Lind, The Spokesman Review, writes about the 37.5 million Americans who have some degree of hearing loss, focusing on the baby boomers who are 20 to 25% of that population.  Lind states that “[t]he American Speech-Language Hearing Association recommends that people age 50 and older have a hearing test every three years.”  She sits in on a hearing exam for 67-year-old Dale Fowler, who came to the University Hearing and Speech Clinic in Spokane, Washington to see if he needed a hearing aid, a visit scheduled at the urging of family members.  Fowler’s exam revealed that he “had some minor hearing loss at high frequencies in one ear, but it wasn’t enough to warrant a hearing aid.”  Fowler’s audiologist, Barbara Peregoy, said that his result was “common among baby boomers.”

Peregoy said that baby boomers often fall into a “gray area,” where they don’t yet need hearing aids but still have some minor hearing loss.  She then explained why people who need hearing aids don’t get them right away (cost, denial, vanity, or fear of appearing older) and the consequences of not addressing hearing loss, noting that hearing loss is a risk factor for dementia.  As for her patient Dale Fowler, although he left without a hearing aid, he did not leave empty-handed–Peregoy handed him a list of good communication skills to help him deal with his minor hearing loss.

Looking For A Quieter Car?

By Daniel Fink, MD

As automobile makers have focused on fuel efficiency to meet federally mandated fuel efficiency standards, interior quiet has suffered.  But it is still possible to find quieter, more comfortable cars.

GM’s Buick Division might be a good place to start.  And these four links offer some other possibilities:

Dr. Fink is a leading noise activist based in the Los Angeles area.  He serves on the board of the American Tinnitus Association, is the interim chair of Quiet Communities’s Health Advisory Council, and the founding chair of The Quiet Coalition, an organization of science, health, and legal professionals concerned about the impacts of noise on health, environment, learning, productivity, and quality of life in America.

Why You Need Less Noise for Work

and Your Health. Belle Cooper has written a very thoughtful piece on the problems with noise at work and play, and the importance of silence in one’s life.  On noise she writes:

Two types of everyday noise can be bad for us. One is excessive noise, such as the prolonged loud noise of being near an airport. The other is simply the distraction of general noise around us, such as conversations or interruptions from colleagues in the workplace.

The former may seem worse, but both can be detrimental to our productivity—and sanity.

Cooper lists a litany of horribles caused by exposure to chronic noise from traffic or airports, like high blood pressure, heart problems, and sleeplessness, but she also explores the effects of everyday noise on those of us not exposed to these chronic noise sources.  What is the effect on those of us who simply experience what she calls “general daily noise?”  She writes:

If you work in an open plan office, you’ll probably find [distraction and interruption] is an even greater problem. Ollie Campbell, CEO of Milanote and part of Navy Design’s multi-disciplinary team, says open plan offices come with their own implicit values. They make team members feel that disruption is acceptable, collaboration is the key priority, and serendipity is worth the interruptions it requires.

Distractions and interruptions are such a common part of our workdays, we don’t even think of them as excessive noise anymore. It’s often more obvious when we don’t hear the noise of distractions around us at work than when we do.. A study at the University of California, Irvine, found that knowledge workers have focus periods of just eleven minutes on average, in-between interruptions. As Campbell said, “if you need to focus, ‘work’ is pretty much the worst place you could be.”

So what can be done to reclaim some peace, to regain one’s focus and concentration?  Cooper suggests that we shut out both excessive/harmful noise as well as “the more general commotion of the modern workplace” so that we can create our best work.  And she’s armed with research that shows that silence doesn’t just relax the brain:

One study of mice found that listening to silence for two hours every day prompted the subjects’ brains to grow new cells in the hippocampus, which is related to our brain’s memory abilities. While new cell growth doesn’t always provide health benefits, in this case those new cells did become new, functioning neurons within the mice brains. In other words, silence could make you a little smarter.

Ok, perhaps that reaching a bit, but Cooper shares some anecdotal evidence that silent time helps us make better long-term decisions as well as spur creative thinking.  In the end, we can’t cocoon ourselves and block out all noise, but when we have the chance, Cooper suggests that we opt for silence.  Sounds good to us!

Fido to human: More Bob Marley, mon.

Your dog thinks your favorite band sucks.

Study finds that dogs are happier listening to soft rock and reggae. Of course, like humans, the preferences weren’t universal, with some pooches preferring other music genres.  But researchers at the University of Glasgow and the Scottish SPCA found that “[r]eggae music and soft rock were found to provoke the most positive changes in [doggie] behaviour.”  This study followed an earlier “2015 study by the same institutions that found classical music had a calming effect on dogs.”  Now that researchers have determined the absolute favorite canine music genres, the Scottish SPCA is planning to “install sound systems in all its kennels to play Bob Marley and Jon Bon Jovi [Ed.: Really?] to their unsuspecting charges.”

Proving once and for all that your dog is cooler than you are.

Consumer Reports looks at affordable solutions to hearing loss:

No More Suffering in Silence? Julia Calderone, Consumer Reports, has written a thoughtful piece about hearing loss and the toll it takes on those who suffer from it.  Calderone states that hearing loss “has long been thought of as an inevitable part of getting older, more a nuisance than a life-altering medical condition—at least by those not experiencing it.”  But that opinion is changing, she asserts, as “the President’s Council of Advisors on Science and Technology (PCAST) and the National Academy of Sciences (NAS) have published reports calling untreated hearing loss a significant national health concern­, one that’s associated with other serious health problems, including depression and a decline in memory and concentration.”

Calderone not only treats hearing loss with the seriousness it deserves, she offers solutions to sufferers, particularly those who can’t afford to buy hearing aids, which “cost an average of $4,700 per pair in 2013.”  This is a very steep price, particularly since hearing aids are usually not covered by health insurance or Medicare.  To help with those who need hearing aids but can’t afford them, Calderone reviews a handful of hearing aid alternatives, namely personal sound amplification products (PSAPs), to see if they can fill the gap for those who need hearing aids but can’t afford to buy them.

Two PSAPs not covered in Calderone’s review are also worth considering: Doppler Labs HERE One and Nuheara’s IQbuds.  Neither company markets their PSAPs as a hearing aid or hearing aid substitute, but at around $300 a pair they offer personal amplification and soundscape management to people who might have no other options.

And a final thought about the sorry state of hearing health in the U.S.: For people who are suffering noise-induced hearing loss (NIHL), the personal and economic costs could have been avoided in the first place because NIHL is 100% preventable.

 

The world sounds different than it did a century ago

and it’s not for a good reason. Claire Asher, BBC, reports on how climate change and animal extinctions have altered the way our world sounds.  Asher writes that human activity is changing our natural soundscape irreversibly:

In 2015, a US team of scientists and engineers reported that the loudest sound in some waters now comes from millions of tiny bubbles, which are released by melting glaciers and icebergs. In the fjords of Alaska and Antarctica, the average noise level is now over 100 decibels – louder than any ocean environment recorded before.

And it is more than our oceans that are affected.  Asher notes that “natural spaces are now polluted with human-made noises. As we change forests into farms and drive species to extinction, we are fundamentally changing how our world sounds.”

The CDC issues report on noise-induced hearing loss

and the facts are frightening. The Centers for Disease Prevention and Control’s (CDC) current issue of Vital Signs focuses on the dangers of noise on hearing health.  Among other things, the report states that:

  • 40 million Americans aged 20-69 years old have noise-induced hearing loss (NIHL). Hearing loss is the third most common chronic health condition in the US, and almost twice as many people report hearing loss as report diabetes or cancer.
  • 1 in 2 American adults with hearing damage from noise did not get it exposure to noise at work. Noise outside of work can be as damaging as workplace noise.
  • Too much loud noise, whatever the source, causes permanent hearing loss.
  • 1 in 4 Americans who report excellent hearing have hearing damage.  You can have hearing loss without knowing it.
  • The louder the sound, and the longer you are exposed to it, the more likely it will damage your hearing permanently.
  • Continual exposure to noise can cause stress, anxiety, depression, high blood pressure, heart disease, and many other health problems.

This fascinating if distressing report comes with easy to understand graphs and charts that clearly explain the dangers of noise exposure, who is most at risk, the high cost of hearing loss, how hearing loss occurs, and, most importantly, what can be done to prevent NIHL.  Because, in the end, one point is crystal clear: noise-induced hearing loss is 100% preventable.

Does the sound of chewing or pen clicking make you enraged?

You are not alone.  Misophonia is a disorder marked by “a hatred of sounds such as eating, chewing or repeated pen clicking.”  It’s not well understood, but the known universe just got a lot bigger thanks to a team of researchers from Newcastle University who have evidence that enraging noises are caused by a brain connection overdrive.

The lead researcher, Dr Sukhbinder Kumar of the Institute of Neuroscience at Newcastle University and the Wellcome Centre for NeuroImaging at University College London, said that, “[f]or many people with misophonia, this will come as welcome news as for the first time we have demonstrated a difference in brain structure and function in sufferers.”   With this news suffers may see the end of one problem they often face; namely, the casual dismissal of their complaints by medical professionals.  As Dr. Kumar notes, “[t]his study demonstrates the critical brain changes as further evidence to convince a sceptical medical community that this is a genuine disorder.”

 

Is nothing safe?

They look so innocent…

Experts Warn Popping Balloons Can Lead To Permanent Hearing Loss. Arrianne Del Rosario, Tech Times, writes about an experiment conducted by researchers at the University of Alberta “to find out how noise from bursting balloons can impact hearing,” and the results were stunning.  The researchers “measured the noise levels from popping balloons in three different ways: poking them with a pin, blowing them with air until they burst, and crushing them until they exploded.”  The loudest bang came from blowing up a balloon with air until it popped.  When it did, it was recorded at almost 168 decibels, “4 decibels louder than a high-powered, 12-gauge shotgun.”

It can’t be that bad, it’s just a balloon, right?  Wrong.  Del Rosario notes that the Canadian Centre for Occupational Health and Safety recommends that “the maximum impulse level should never go beyond 140 decibels.”  She adds that “[c]onstant exposure to noise, even as low as 85 decibels — for example, the noise from cars honking their horns in a city traffic — can make a person vulnerable to hearing loss.”

Del Rosario is right that damage to hearing can occur well under 140 decibles, but wrong to imply that damage only occurs at 85 decibels or higher.  85 decibels is the industrial-strength occupational noise exposure standard. Auditory damage can begin at only 75-78 decibels.  The only evidence-based safe noise exposure level is the EPA’s 70 decibel time weighted average for 24 hours.  Cautions noted noise activist Dr. Daniel Fink, “If it sounds too loud, it is too loud.  Hearing is an important social sense, and once cochlear hair cells and auditory synaptic junctions are damaged, they are gone forever.”

Whatever the decibel reading, the problem is that each exposure to loud noise leaves a mark.  As one of the researchers, Bill Hodgetts, advised:

Hearing loss is insidious — every loud noise that occurs has a potential lifelong impact. We want people to be mindful of hearing damage over a lifetime, because once you get to the back end of life, no hearing aid is as good as the once healthy built-in system in your inner ear.
